A network analyst is investigating a potential data exfiltration. The logs show large outbound transfers to an external IP over HTTPS. The analyst suspects the traffic is encrypted and cannot see the content. What is the best next step?

Deploy a TLS interception proxy to decrypt and inspect the traffic.

Ignore the traffic because HTTPS is secure.

Request the external IP's certificate to verify the domain.

Block the external IP immediately.

A small office wants to secure its Wi-Fi network. The router supports WPA2 and WPA3. Most devices are modern, but a few older devices only support WPA2. What is the best configuration to maximize security while ensuring all devices can connect?

Disable security and rely on MAC filtering.

Use WPA3-only and require older devices to be replaced.

Enable WPA3 with a transition mode that allows WPA2 devices to connect.

Use WPA2-only to ensure all devices can connect.

A company wants to segment its network to protect sensitive servers from the general user network. They plan to use a firewall to control traffic between segments. Which firewall type is best suited for this purpose?

Host-based firewall on each server.

Proxy firewall for all traffic.

Stateful firewall with application-layer inspection.
